title: Retinal arterial macroaneurysms.
abstract: Retinal arterial macroaneurysms are acquired saccular or fusiform dilatations of the large arterioles of the retina, usually within the first three orders of bifurcation. They are associated with systemic vascular conditions such as hypertension and arteriosclerotic disease occurring most commonly in elderly women. The primary reported symptom is a sudden loss of vision due to haemorrhage or oedema affecting the macula. Most of macroaneurysms regress without treatment and without causing decreased visual acuity. Poor visual outcome may occur secondary to foveal exudates and subfoveal haemorrhage.
